Units explained
Tola
The tola equals 180 troy grains, about 11.6638 grams (three-eighths of a troy ounce).
From Sanskrit 'tula', meaning a balance or weighing.
The primary unit for gold and silver across India, Pakistan, and Nepal.
Fixed at 180 grains under British India in 1833.
Earth's Mass
The Earth mass (M(E)) is about 5.976E24 kg.
Adopted as a convenient unit for the masses of terrestrial planets.
Astronomy and planetary science.
Refined over centuries since Cavendish first 'weighed the Earth' in 1798.
